I find the out of focus rendering of the 17mm F1.8 to be very smooth, creamy and pleasing to look at. I remember complaining about the Panasonic 20mm F1.7 for having very harsh bokeh and distracting out of focus rendering, even at F1.7 widest open aperture. I am glad to see Olympus 17mm can create much more pleasing out of focus look in the image.

So if it is a simple error fair enough but does seem somewhat inconsistent...
